Abstract
Embodiments relate to constructing a three-dimensional model using a plurality of two-dimensional photographic images. In a first embodiment, a first user input specifying a first position on a first photographic image may be received. A second user input specifying a second position on a second photographic image may be received, the second photographic image having a second perspective, specified by a second set of camera parameters, being different from a first perspective of the first image specified by a first set of camera parameters. The user inputs may indicate corresponding features in the images. Using photogrammetry, a point in a three-dimensional space may be determined according to the first position, the second position, the first set of camera parameters, and the second set of camera parameters. A surface of the three-dimensional model may be determined, whereby the surface may be curved to the point in three-dimensional space determined earlier.
